Does exist a stable, old, low temperature version of Armbian for OPi1

[psygnosis]

Hi,
I have 2 OPi1 that I want to use for some test projects.

One project consist just on PiHole, the other one on Tailscale.

Since with newer kernel I have high temperature on idle (like 70°C) can you advice me an old version that maybe has a "better" thermal management?
Thank you so much, if I'm saying something stupid please tell me, maybe I just need to tune something like disable hdmi, gpu etc...

@psygnosis Which version of Armbian and os are you running? Yesterday I loaded  current noble on a test system and I just noticed that it is running hot (45) even with a significant heat sink.  Another operational system that is running current bookworm runs much cooler (32). If you are running noble, could I ask you to try bookworm to see if there is a difference.

 

I will load up my test system with bookworm to check also.
